Description

The ToolDocker WT-JGS Small Diameter Straight Diamond Router Bit ( $8\text{ mm}$ ) is an industrial vacuum-brazed router tool engineered for tight internal corner routing, sink cutout milling, deep slotting, and edge trimming on engineered quartz, granite, marble, sintered stone, and porcelain slabs. With an $8\text{ mm}$ cutting diameter, rounded transition nose, and a deep $40\text{ mm}$ diamond working height supported by a rigid $1/2''$ shank, it allows smooth plunge cuts and chatter-free milling in hard stone materials.

Key Features

Compact $8\text{ mm}$ Head with Rounded Tip: Designed for tight-corner sink cutouts, internal radius routing, deep narrow slotting, and smooth plunge entries.
Extended $40\text{ mm}$ Cutting Height: Clears full-depth 2 cm and 3 cm stone slabs and multi-layer laminated countertop edges.
Heavy-Duty $1/2\text{''}$ ( $12.7\text{ mm}$ ) Shank: Stepped neck design provides rigid support, absorbing high-torque loads and reducing tool deflection during deep milling.
High-Grade Vacuum-Brazed Diamond: Coarse industrial diamond grit delivers fast linear feed rates, smooth sidewall finishes, and long edge life.
